The seeds contain a polysaccharide glucomannan.All parts of the plant are used for allergic disorders. Alcoholic extract of the plant was found to inhibit passive cutaneous anaphylaxis (PCA) in experimental animals. The inhibition was comparable to standard drugs used for allergy and bronchial asthma.Ethanolic extract of the leaves, flowers and seeds demonstrated strong stimulation of antigen specific and non-specific immunity in mice.The 50% ethanolic extracts of the leaves, flowers, seeds and roots were found effective in treating caecal amoe- biasis caused by Entamoeba histolytica in rats. But the extracts did not exhibit direct amoebicidal activity in vitro against trophozoites of the parasite.The iridoid glucosides showed an- tileishmanial activity both in vivo and in vitro.

Plant—toxic on the nervous system.The flowers contain flavonoids including quercetin, kaempferol, api- genin. Cardiac glucoside, nymphalin, showed sedative action in small doses.The petroleum ether extract of the plant of Nymphaea species, given at a dose of 300 mg/kg i.p. prevented necrosis of the liver tissue and promoted, to some extent, liver regeneration in CCl4-induced toxicity.
